It would be interesting to see how Japan recovers economically relatively to the US post Corona crisis.
There are many, many contexts and scenarios where this exact same sentence can be said in a highly negative way. In this instance it is great, but I can assure you that many Japanese workers experience the dark side of this mindset (e.g., stay in the office as long as possible; don't "shirk duties" by taking time for yourself; god help you if you're a woman; etc.).
I have no doubt this is not everyone's experience, but it's also not uncommon.
What we can do is to learn how companies solve the problem.
Was the layoff necessary? Was the form of the layoff necessary?
Probably not. Probably with all those billions of investments you could have made choices that will leave you with more than paper thin margins or maybe you could beg your investors for more to keep the company afloat.
This could have easily be a formative experience for the company bringing everybody together and motivating for years.
